Leaf mould (Mycovellosiella fulva)
(c) Elizabeth Bush Virginia Polytechnic Institute and State University, 2013
Symptoms of leaf mould are pale-green or yellowish areas with undefined margins that appear on the upper leaf surface. Under humid conditions the lower leaf surfaces of the spots become covered by an olive-green to greyish-purple velvety growth of the fungus.
| What to do: Prune and stake to reduce humidity. Avoid excessive shading by providing adequate plant and row spacing. Avoid wetting leaves when watering. |
